Application June 20, 1933, Serial No. 676,730

3 Claims.

The invention relates to a hand sharpening implement and more especiallya razor blade sharpener.

The primary object of the invention is the provision of a sharpener ofthis character, wherein a knife edge blade can be sharpened in aconvenient manner, the sharpener being hand manipulated and capable ofadjustment to vary the sharpening action thereof when in use.

Another object of the invention is the provision of a sharpener of thischaracter, wherein safety razor blades can be easily sharpened withdispatch, these either of the double or single cutting edge type, thesharpener being of novel form and readily and easily handled when in useand assuring sharpening of the blade.

A further object of the invention is the provision of a sharpener ofthis character which is extremely simple in construction, thoroughlyreliable and efiicient in its purpose, convenient for handling,susceptible of accommodating cutting blades of the safety razor type,and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of the sharpener constructed in accordance withthe invention, showing by dotted lines the hands of a user and by fulllines a safety razor blade in position for the sharpening thereof. 1

Figure 2 is a top plan view.

Figure 3 is a view similar to Figure 1 showing the sharpener in openposition.

Figure 4 is an inner face view of one cheek part of the sharpener.

Figure 5 is a perspective view of the spring for the sharpener.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the sharpener comprises a pair ofcheek members or plates 10, these being alike and preferably ofsubstantially rectangular form. Each member or plate 10 is formed withan extension or arm 11 at the heel edge and medially thereof. The arm atits free end is formed with a notch 12 constituting a seat for a purposepresently described.

Straddling the arms 11 of both members or plates 10 at the free ends ofsaid arms is a substantially U-shaped leaf spring 13 which has its limbs14 riveted or otherwise secured at 15 to the arms 11, while the bow orbight portion 16 of this spring is reduced in width and occupies theseats 12 in the free ends of the arms 11 so as to avoid lateral swingingmovement of such spring or disalignment of the arms 11 with relation tothe spring in the assembled condition of the sharpener.

The cheek members or plates 10 at their inner opposite faces carryleather pieces or slabs 17 for action upon the cutting edge of a safetyrazor blade 18 or other cutting blade for the purpose of the sharpeningof the same or the reconditioning thereof.

In the use of the sharpener the same is placed preferably in the lefthand of a user as illustrated at A, while held in the right hand asillustrated at B in the drawing is the blade 18 to be sharpened. Thelatter is placed between the pieces or slabs 17 as clearly shown inFigure 1 of said drawing. The thumb and index finger of the hand A exerta pressure on the cheek members or plates 10 against the opening actionof the spring B and thus in this manner proper contact under pressuremay be had upon the cutting edge of the blade 18 for the sharpening orreconditioning thereof. By sliding the blade 18 between the pieces orslabs 17 of the sharpener, sharpening action will take place for thesharpening of the cutting edge of said blade.

What is claimed is:

1. A sharpener of the character described comprising a pair of cheekshaving leather pieces at their inner opposite faces, arms extending fromsaid cheeks, and a spring straddling the arms crosswise of their freeends and made fast to said arms, the free ends of the arms being notchedto provide seats for the spring.

2. A sharpener of the character described comprising a pair of cheekshaving leather pieces at their inner opposite faces, arms extending fromsaid cheeks, a spring straddling the arms crosswise of their free endsand made fast to said arms, the free ends of the arms being notched toprovide seats for the spring, and fasteners securing the ends of thespring to the arms.

3. A sharpener of the character described comprising a pair of cheekshaving leather pieces at their inner opposite faces, arms extending fromsaid cheeks, a spring straddling the arms crosswise of their free endsand made fast to said arms, the free ends of the arms being notched toprovide seats for the spring, and fasteners securing the ends of thespring to the arms, the straddling portion of the spring relative to thefree ends of the arms being reduced for reception in the seats.
